This invention relates Ito the bearings of i p n g-C uple qfal t ngr r and us'e gthem;

tothe means for supporting same and adg; The principal object ofthe invention isto provide a simple/arrangement for supporting the impression andfplatecylinders', and at the same time locating the impression cylinders indefinite positi'ongand providing. for

310 the adjustmentlof the plate cylinders toward and from them without necessitatingprecise positioning during manufacture or accurate I-machine workg v I a II I I Reference is to be had pto the accompany- E:1,5 ing drawingsyinfwhich "I 1 Fig. 1 is a sidelview of part of a printing press showing a preferred form of the invention and showing the shafts -in sectionon a planejust outside the frame Fig.2 is a plan; and

\ Figs. 3 and I4 are endgviews of the plate ylindergand impression cylinder bearings respectively. I V l a i I haVBTShOWIl theinvention asapplied to r: g a web perfectingipresshavingtwo plate cylinders and two; impressioncylin'ders 11.. j For supportingthesecylinders have provided the frame "with rough cast vunfinished I perforations in which, are l cast permanent 3.1. bushings1500 ofjbearing metal having aligned bearing surfaces linisl ed'in the act-of cast- .ing. I They constitute' Imeans for carry ng studs or shafts 151.v On' eachof theseshafts 151 are pivotally supported bearing plates 152. Each ofthesebearing plates carries an impressioncylinder bearingpreferably in" the form of a lining 153, of soft metal cast in the bearing plate; These two bearings. at opposite sides of the press carry one ofth'e iinpression cylinders. It will be noted that they project upwardly from the pivotal" shaft'151- which supports them.

- "Beyond these'are another "similar set of,

" shafts or studs 154 cari'ied in theframe and supporting a pair of bearinglplates155 proe jecting upwardly iinzthe sameway. These have plate cylinderbearings156;0f softmetal v j j I p cylindersofthe two printing couples may be arranged in alginmentr tions in alignmentwith'each other and are 1 provided with a bushing158 of soft allo'ycast therein withjfini'shed surfaces. ,7 Each bushin'g158 is a complete cylinder with a'Iflat flange at one endor both. Through these extends a screw rod 159 one'being located on each side of the'machi'ne. 'Each' screw rod passes through perforations 160 and 161 in the bearing plates 155 and 152 respectively, the former perforation being smooth and the regulating th'e'pressure of each coupl'e.

1he'shats151and lmfare mountedinth e {bushings for 'bearings15'00 which are formed of suitable metal andrcast' in finished position on 'thefrarne'of th'e machine around master 7 1s liafts'01i'studs so as to lineup the said bushiings. Thus, the machining and "finishing of the frame for. the purpose of'supporting these I shafts isIentirely avoided Also by mounting the cylindersnot'on' these shafts 154and 151, but on shafts pivotally supportedthereon,

theadju'stment 'of the cylinders is provided for without any finishing or machining. a, Of

course the studs of thecylinders themselves are mounted in the'be'aring bushings 153 and 1 56 cast'in the bearing plates 152 and155 a finishedc'ondition soas just to vfit the studs of the I cylinders. All finishing therefore is eliminated at this point. Theadditional adjust ingfrods 1591 are also so mounted that there isno finishing of the'machinei frame in order to mount them position and adjust the cylinders by their aidl" It willbe obvioustherefore that all the brought into correct operativefrelation by no precise positioning of the parts during manufacture such as machining of the frame and fitting the parts. The frame is simply cast with holes or passages through which the studs are to pass. These passages are simply cast in 'a rough state larger than they are to be made eventually. They need not be smooth or even accurately located with respect to each other. Thiseconstitutes a material economy in the manufacture and setting up of the press besides securing a very accurate and conveniently operated adjustment for the plate cylinders.

Although I have illustrated and described only one form of the invention and shown it as applied to only one formof press, I am aware of the fact that modifications can be made therein by any person skilled in theart Without departing from the scope'of the 1nvention as expressed in the claims. Therefore I do not wish to be limited to all the details of construction herein shown and described, but

\VhatI do claim'is a V V 1. In a printing press, the combination with a printing couple, of means for supporting both of. the printing cylinders on axes below the'centers of the cylinders, and means for-positioning the said cylinders with relation to. one another located above the level ofgthe said supporting means. u 2. In a printing press, the combination 7 with the plate andimpression cylinders, of

pivotallymounted bearings for each of said cylinders, and adevice for ad usting the bear- ;ings of both cylinders about them pivots toward .or from eachother. I

means for adjusting both cylinders. toward each other thusmaintaining the paper line at the same point after any adjustment.

13. In a perfecting printing press, the combination with two printing couples arranged substantially in alignment, of means for adjusting the two cylinders of each. couple simultaneously into closer or more distant contact to change their pressure on the paper but not the position thereof. V e
